Several substituted xanthones have been synthesized and tested for herbicidal activity. Both the classical Michael-Kostanecki method and a new regioselective method were used to prepare starting 1-hydroxyxanthones from which several 1-alkoxyxanthones were prepared. Among the compounds tested, herbicidal activity was greatest for 1-methoxyxanthone and 1-(allyloxy)xanthone. Some species specificity was observed, particularly for 1-methoxy-3-methylxanthone, which was more toxic to grasses than to broadleaf species.
